i Application filed April 1B, 1902. Seria-1blu. 108,562. (No model.)

To @ZZ whom t may concern.:

Be it known that I, LORING GOES, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvementin Wrenches, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The object of my present invention isto provide a screw-wrench of efficient capacity and economic construct-ion; and myinvention consists in a wrench embodying in its structure the combined4 features and improvements particularly explained in the following detailed description and dei-ined in the summary and as illustrated in the accompanying drawings, whereinc Figure 1 represents a side view of my improved wrench; Fig. 2, a front view of the same, a portion of the handle being shown in section. Fig. 3 is a transverse section at line W W in Fig. 1. Fig. tis a longitudinal sec; tion of the movable jaw and its integral screw extension. Fig. 5 is a transverse section at line X X, and Fig. 6 a transverse section at line Y Y, on Fig. l. The sections are assumed as looking in the direction of the arrow on their respective lines.

Referring to the several parts of the wrench as shown on the drawings, the letter A indicates the wrench-bar, which may be of wellknown form, as heretofore employed in' a Coes 7 wrench, and comprising a plain rectan gular bar portion having formed upon one feature of my invention, is constructed as' shown. It has a strap b and opposite side lips b', that embrace the wrench-bar, while the under body B2 of the jaw is adapted for seating against the front edge of the bar A, and said jaw-body is provided at its lower end with an integral screw-threaded extension C in alinement, coincident with, and

continuingthe rounded front outline ot' the body portion and longitudinally parallel with the wrench-bar and adapted as a support and screw for adjusting said movable jaw and u pholding it against the strains when in action.

The handle H is preferably made as an allmetal piece internally fitted for rigid support upon the 'bar-shank A and provided at its collar portion with a projecting step F, having a metal-surrounded opening or circular hole e therethrough, that serves as a guide for the screw C forward of the main body of the handle, and with a seating-surface f upon the top of said step perpendicular to the axis of said opening e. An annular internallythreaded and externally-'checked rosette or nut D is rotatively arranged upon the screw C, which latter when the parts are assembled extends through the guide-opening e, and the rosette is supported against the seating-surface f upon the step F, the periphery of said rosette standing entirely forward of and clearing the plane at the front face of the rectangular portion of the wrench-bar. A suitable retaining member or abutment G is provided for overhanging engagement with the rosette or nut D, and thereby confining said rosette in adjacent relation to its seating-surface, while permitting its free rotative movement about the threaded extension C for adjusting the jaw B. The abutment G may be formed or carried on the bar A, or the metal of the handle may be extended for overhanging the rosette, as indicated by the dotted lines at h on Fig. 4, a forwardly-projecting portion of the handle forming the abutment G and wholly surrounding the screw.

As a means for securing the all-metal handle-piece H to the bar-shank and rendering it tirmly seated against the positioning-shoulders d there is arranged in the present instance a transversely-disposed cylindrical pin I, which is inserted in an opening through the handle and bar-shank, and after assembling the ends of said pin are indented, as at m, in a crescent form and in a manner to throw the metal of the pin at n toward the top end of the handle, and thereby crowding the handle up the shank and tightening the top end of the handle-piece rmly against the shoulders d. The handle-piece is made with opposite internal bosses s, which match IOO against the bar-shank and give solid metal about the pin-opening.

I claim and desire to secure by Letters Patent- LA Wrench constructed as hereinbefore described,comprising the rectangular wrenchbar provided with the fixed jaw, and having the laterally-reduced bar-shank With front and rear handle-supporting edges and positioning-shoulders, the metal handle-piece or frame rigidly tting upon the bar-shank along its front and rear edges and against said positioning-shoulders, said handle-piece being provided at its upper end with an integral for- Ward projection having a hole therethrough parallel with the bar-shank, the movable jaw having a strap and lipped downwardly-extended body portion sliding on said wrenchbar, and an integral screw-threaded extensionin eontinuingalinement with the rounded front of the body and passing through said handle projection, a rosette arranged on said screw-threaded extension with its periphery forward of the front plane of the bar, and a retaining member xed inthe front edge of the bar and projecting over the rosette, al1 substantially as and for the purposes set forth.

2. In a Wrench, in combination with the Wrench-bar having handle-positioning shoulders, and a handle-supporting bar-shank, an al1-metal handle-piece mounted on said barshank, and a fastening-pin inserted transversely through said handle-piece and barshank, and having its ends indented and upwardly defiected for forcing said handle-piece against the positioning-shoulders, substantially as set forth.

3. In a wrench, the combination as described, of the Wrench-bar carrying the fixed jaw and the laterally-reduced bar-shank having handle-supporting edges approximately the full length of Vsaid shank, the movable jaw slidably embracing said Wrench-bar and having an under body seating parallel against the front 'of said bar, and a screw-threaded extension continuous with said under body, the rotatable rosette-nut arranged thereon forward of the front plane of the bar, the oval tubular handle-piece internally fitting the edges of the reduced bar-shank, and provided With a projecting collar-guide surrounding and carrying said screw-threaded extension outside the handle, and forming an end seat for the rosette, a projecting detent upon the front face of the wrench-bar engaging over the edge of the rosette, and means securing said handle-piece rigidly to the barshank, substantially as set forth. l

Vitness my hand this 15th day of April, 1902.

LORING GOES.
